I'm trying to use this library to access my company mainframe and automate some processes.

But when i try to connect with Open3270 a get a different screen from when i use another TN3270 software like x3270 or PASSPORT HIO.

I'm using the same config on both of then, and keep getting a "Authorization Verification" screen on Open3270.

Some one could finger what I'm doing wrong?

Not sure if you are still reading this discussion, but if so, post me some more detail and I will see what i can do for you.  I have been using this to screen-scrape my company's mainframe for over a year now.

I have a similar problem. Let us know how do you have solved your problem!

I did not solved the problem, my solution was buy a Attachmate Extra copy.

how about providing a screenshot of the 3270 retail vs the Open3270 library so we have something to go on.  You haven't given me enough information to even begin trying to help you

Sorry, i'm complaining, Open3270 is a great initiative.
But i'm not a expert on terminal's and for me was faster buy a complete solution. The problem could be my company's mainframe.

I'm not having much time to debug again and take some evidences, but as soon i could get some i'll post here.

Thx a lot.

I was wondering if you ever got anywhere on this, or had any screenshots or debug log to look at
